6ceeb6902a utmp.ut_time and lastlog.ll_time are explicitly int32_t rather than 
time_t.  Deal with the possibility that time_t != int32_t.  This boils
down to this sort of thing:
 -   time(&ut.ut_time);
 +   ut.ut_time = time(NULL);
and similar for ctime(3) etc.  I've kept it minimal for the stuff
that may need to be portable (or 3rd party code), but used Matt's time32
stuff for cases where that isn't as much of a concern.

7c2274dc95 The pam_krb5 module stored a reference to a krb5_ccache structure as 
PAM module state (created in pam_sm_authenticate and referenced later
in pam_sm_setcred and pam_sm_acct_mgmt).  However, the krb5_ccache
structure shares some data members with the krb5_context structure
that was used in its creation.  Since a new krb5_context is created
and destroyed at each PAM entry point, this inevitably caused the
krb5_ccache structure to reference free'd memory.

Now instead of storing a pointer to the krb5_ccache structure,
we store the name of the cache (e.g. `MEMORY:0x123CACHE') in
pam_sm_authenticate, and resolve the name in the other entry points.

This bug was uncovered by phkmalloc's free'd memory scrubbing.

88c8bcce6c Use krb5_get_err_text' instead of error_message' so that instead of 
e.g.

   Unknown error: -1765328378

we get

   Client not found in Kerberos database

Another way to accomplish this would have been to leave
`error_message' alone, but to explicitly load the Kerberos com_err
error tables.  However, I don't really like the idea of a PAM module
dorking with global tables.

195426c211 Introduce 'exempt_if_empty' option to pam_wheel(8), which bypasses the 
group membership requirement if the group has no explicit members listed
in /etc/group.  By default, this group is the wheel group; setting this

68e6e4bd40 Since pam_get_authtok(3) doesn't know about our options structure, setting 
the PAM_ECHO_PASS option on-the-fly is a NOP (though it wasn't with the
old pam_get_pass(3) code).  Instead, call pam_prompt(3) directly.  This
actually simplifies the code a bit.

f748a713da PAM modules shouldn't call putenv(); pam_putenv() is sufficient. The 
caller is supposed to check the PAM envlist and export the variables it
contains; if it doesn't, it's broken.

9201dc40bf Change the order in which pam_sm_open_session() updates the logs. This 
doesn't really make any difference, except it matches wtmp(5) better.

Don't do anything in pam_sm_close_session(); init(8) will take care of
utmp and wtmp when the tty is released.  Clearing them here would make it
possible to create a ghost session by logging in, running 'login -f $USER'
and exiting the subshell.

53f3167d07 Add a PAM module that provides an account management component for checking 
either PAM_RHOST or PAM_TTY against /etc/login.access.o

This uncovers a problem with PAM_RHOST, in that if we always set it, there
is no way to distinguish between a user logging in locally and a user
logging in using 'ssh localhost'.  This will be fixed by first making sure
that all PAM modules can handle PAM_RHOST being unset (which is currently
not the case), and then modifying su(1) and login(1) to not set it for
local logins.

- Spam /usr/lib some more by making libssh a standard library.
- Tweak ${LIBPAM} and ${MINUSLPAM}.
- Garbage collect unused libssh_pic.a.
- Add fake -lz dependency to secure/ makefiles needed for
  dynamic linkage with -lssh.

03adba96a0 Further changes to allow enabling pam_opie(8) by default: 
- Ignore the {try,use}_first_pass options by clearing PAM_AUTHTOK before
   challenging the user.  These options are meaningless for pam_opie(8)
   since the user can't possibly know the right response before she sees
   the challenge.

 - Introduce the no_fake_prompts option.  If this option is set, pam_opie(8)
   will fail - rather than present a bogus challenge - if the target user
   does not have an OPIE key.  With this option, users who haven't set up
   OPIE won't have to wonder what that "weird otp-md5 s**t" means :)

9f5b04e925 Style improvements recommended by Bruce as a follow up to some 
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.
